I recently had some DNS issues so in an event to rectify the problem I uninstalled DNS from all my DNS servers and then reinstalled DNS again.
I have a single 2003 domain with 3 primary DNS servers that are also DC’s. Replication between them seems to be fine. However an intermittent problem occurrs where a name is not resolved.
When i open DNS and look at the Forward Lookup Zone i see the following:
yourdomain.com
—>_msdcs
—>_sites
—>_tcp
—>_udp
—>…
The forward lookup zone is identical on all 3 DNS servers. There is no _msdcs.yourdomain.com above yourdomain.com
The _msdcs below yourdomain.com is not a delegation (not greyed).
How do I go about getting the _msdcs.yourdomain.com zone back??
Should the forward lookup zone look like this:
_msdcs.yourdomain.com
yourdomain.com
—>_msdcs
—>_sites
—>_tcp
—>_udp
—>…
I don’t quite understand this whole _msdcs thing.
